IMPROVEMENT IN SELIF-FAC.'lllNG- SPINNING-MULES.`

Specification forming part of Letters Patent No. 155,749, dated October 6, 1874 application filed April ce, 1813.

To all whom it may concern:

Be it known that I, SAMUEL PLATT, of Oldham, in the county of Lancaster, Kingdoni of Great Britain and Ireland, -.h\ave in- 'vented Improvements in the Oonstructiorkoi1 Self-Acting Mules and Twiners for Spinning and DoublingGotton and other Fibrous Substances, of which the following is a speciiication:

This invention is intended to be used as a substitute for the ordinary nosing motion in self-acting mules and twiners; andits ob- .ject is to stop the revolution of the spindles instantly at the close of the backing off, before the change is made for the going in of the carriage and the winding on of the yarn. By these means no more yarn is. backed off the spindles than is absolutely necessary, and the point or nose of the cop is prevented from becoming loose or soft.

The invention consists, principally, in the use of a ratchet-wheel fixed to or formed with the rim-shaft or rim-block in combination with a click or ratchet-lever, which is thrown into gear therewith, so as to lock the rim-wheel, and thus stop the spindles, by the action of the second-change lever or backing off catch on the boot-leg shaft. The ratchetlever or click is so connected to the secondchange lever that it is thrown into gear with the teeth of the ratchet-wheel the instant that the backing oif is completed, and before the change is `effected for winding on.

In order to enable others skilled in the art to make and use my invention, I will now proceed to describe more in detail its construction and operation.

My invention may be applied in different ways in various forms or arrangements of self-acting mules or twiners, but by way of illustration I will point out what I consider the best way to apply my invention to what is known as a Platt mule or twiner, and it will be evident to any practical mechanic that only a slight variation will be required to adapt it to other forms of self-acting mules or twiners.

On reference to the accompanying drawing, which forms a part of this specification, Figure lis a side view of so much of the headstock of a Platts mule (old pattern) as is requisite to show the application of my invention thereto, and Fig. 2 is a similar view, showing the modification required to adapt it to the more modern arrangement of the same mule. Fig. 3 is an end view, and Fig. \4\a plan view, on a larger scale, of the parts iat therback of the head-stock; and Fig. 5 is a side v1`ew, still further enlarged, of the arrangement for lifting and releasing the catchlever.

a. a is part of the headstock framing; b b, the boot-leg shaft; c c, the rimslpaft, and d d the rim-wheel. Fixed to the boss of. the second-change lever c e,'on the boot-leg shaft b b, at the front of the head-stock, or cast in one piece with it, I have a second lever, ff, prolong rod, g g, which extends through to the back of the head-stock, where it is provided with an inclined projection, h h, (see'Fig. 5,) which, when the rod g g is thrust backward by the lever f f, passes under a finger or catch, i c', attached to the ratchet-lever or click 7c 7c by a bracket, l l. This fin ger or catch it is jointed, so that it gives way as the inclined projection h h passes under it in the direction of the arrow. But just before` the completion ofthe backing off the change or backing-oli' lever e e is released, and a strong spring, m m, or a weight acting on the lever e e, draws the long rod g g forward in the direction of the dotted arrow, and the inclined projection h h at its rear end, coming against the finger i c', which is rigid in this direction, raises the ratchet-lever or click la k into gear with the teeth of the ratchet-wheel n n, which is fixed on the rim-block o o, and thus instantly stops the rim-wheel d al, and prevents the spindles from making any more turns backward. As soon as the inclined projection h h has passed the linger t' i the ratchetlever k 7c falls out of gear. The third change now takes place, and the carriage immediately commences to run in77 to the rollers and the spindles to revolve and wind on the yarn.

To prevent accidents the long rod g gis not coupling, q q, in the center. It will also be seen, on referring to Fig. 2, that in the more modern pattern of this mule, as the motion of the second-change lever e eis in the reverse jecting upward, and having attached to it a 4 entirely rigid, but is provided with a spring-4 direction, the rod g g is made in two parts, in the manner 'and for the purpose herein'deconnected together by a lever7 r 1.

I claim as my invention- The ratchet-wheel n, fixed to or formed. with the rim-block or rim-wheel d, in combinati on with a click or ratchet-lever, k, which is thrown into gear therewith just before the completion 0f the backing 0E, so as instantly to stop the rim-wheel and prevent the spindles from making any more turns backward, substantially In testimony whereof I/have signed my name to this specification in the presence 0f two subscribing witnesses.

SAMUEL PLATT.
